Missing fixes for CVE-2021-40438 and CVE-2021-26691 in the versions of httpd, as shipped in Red Hat Enterprise Linux 8.5.0, causes a security regression compared to the versions shipped in Red Hat Enterprise Linux 8.4. A user who installs or updates to Red Hat Enterprise Linux 8.5.0 would be vulnerable to the mentioned CVEs, even if they were properly fixed in Red Hat Enterprise Linux 8.4. CVE-2021-20325 was assigned to that Red Hat specific security regression and it does not affect the upstream versions of httpd.
